IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part -of Letters Patent No.43,390, dated July 5,1.864.

To @ZZ whom t may concern:

Be it known that 1, J. N. OLEES, of Darbyville, in the county ofPickaway and State of Ohio, have invented a new and ImprovedGrain-SeparatingMachine5 andI do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of this specication, in which-Figure 1 is a longitudinal vertical section of my invention, takenA inthe line a a', Fig. 2. Fig. 2 is a transverse vertical section of thesame, taken in the line y y, Fig. l. Fig. 3 is a transverse verticalsection ofthe same, taken in the line e z, Fig. l. Fig. 4 is a plan ortop view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to a new and improved grain-separator designedchieiiy to be applied to thrashing-machines and to operate conjointlytherewith, so that the grain may be thrashed and cleansed or separatedfrom all impurities at one and the same operation.

To enable those skilled in the art to fully understand and construct myinvention, l will proceed to describe it.

A represents a box or case which incloses the working parts ofthemachine, and which may be constructed in any proper manner. In the upperpart of this box or case A there is placed an inclined rotatingscreen,B, one part, a, of which is provided with wire-cloth of a linemesh to admit of foreign substances smaller than wheatV passingthrough-it-such, for instance, as sand, smut, cockie, chess, 85e. Theother portion, b', is provided with wire cloth having a meshsufficiently coarse to ad- .mit of wheat passing through it, but notpart h of the screen and falls into a trough, ll), in which ascrew-conveyer, E, is placed. This conveyer may be constructed in theusual way, and from it the screen is rotated by means of a belt, d,which passes around pulleys e e at the ends of the shafts fj' of thescreen and conveyer, as shown in Fig. 1. The conveyer E Vnieves thewheat along in the direction indicated by the arrow l, and discharges itupon a chute, g, which conducts it into the lower end, h, of a suctionblast-spout, F, which is at one end of a fan-box, G, the lattercommunicating with the part t' of the blast-spout by means of anopening,j. The lower end of the part z of the blast-spout is providedwith a flap, 7c, opening outward, as shown in Fig. 2, and in the upperpart of there is placed a horizontal slide, l, by adjusting which thestrength of the blastin F may be regulated as desired. The two parts ht' of thc blastspont are placed side by side and connected at theirupper ends by an arched or curved passage, as shown in Fig. 2. The soundwheat, on account of its superior gravity, is able to resist the actionofthe blast in the part 7L of the spout F, and it consequently fallsfrom h into a hopper, El, which conducts it into a bag or any receptacleprepared to receive it. The light impuritiessuch as dust, smut,shrunkengrain, &c.is carried up the part h bythe blast, and the heavier portionsof such substances fall to the bottom of i, while the lighter portionsare drawn into the fan-box Gr, and expelled from the lower' part of theouter side thereof. The red arrows in Fig. 2 show the direction of theselight impurities and the black arrows show the direction of the shrunkengrain, Ste. The latter accumulate in the bottom of the part i of F, andare discharged from time to time therefrom as their weight becomessufficient to open the iiap k.

This device is placed on the top of a thrashing-machine, and the grainis delivered into the elevated end of the rotary screen B by means ofsuitable elevators.

The device has been practically tested,

and performs its work in a perfect manner.

i Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is Y The rotating screen B, composed ot' afine and of a coarse portion, a b, the spiral conveyer E, and'blast-spout F, all arranged and combined to operate in the mannersubstantially as and for the purpose herein set forth.
